My Career in Parapsychology
Etzel Cardeña

Etzel Cardena I was quite literally born into parapsychology. My father was a psychoanalyst and parapsychologist in Mexico City, and I can recall how I would listen as a child to the fascinating conversation between my parents about parapsychology books (I recall books by J. B. Rhine and Les Povouirs Secrets de l’Homme by Robert Tocquet). My father eventually integrated his studies of hypnosis with those of parapsychology, and gave workshops on this area, in addition to carrying out some informal psi research and writing some booklets on the topic with one of my older brothers. (Photograph taken by Ulrika Oredsson.)

As a teen I witnessed some people who seemed to display clairvoyant abilities, although I did not sense that I myself had had any unusual experiences until I started working in very shamanically-oriented experimental theatre. At that time I was getting a licenciate in clinical psychology and found out that my regular studies did not explain any of the unusual states of consciousness I was experiencing, at which point I decided to change my emphasis from clinical psychology to the study of consciousness.

I finished my studies at the Universidad Iberoamericana in México and after working professionally in theatre for a couple of years, left to get an MA in clinical psychology at York University in Toronto, Canada. I had originally chosen York because a course on the psychology of consciousness was scheduled, but it was cancelled at the last minute, and after getting my MA I fulfilled a dream by going to work with Charles (Charley) Tart, perhaps the foremost researcher in altered states of consciousness and parapsychology. I got an MA and PhD in Personality Psychology at the University of California, Davis, under Charley, with a dissertation on the phenomenology of deep states of consciousness. From Davis (where I also learned about the conceptual complexities of consciousness from Thomas Natsoulas), I became a postdoctoral fellow and resident scholar at Stanford University, where I concentrated on dissociation (alterations of
consciousness related to experiential detachment) and hypnosis under another great figure in the area, David Spiegel. Since then I have been a full-time professor in psychology in various universities (including Georgetown University), most recently Chair and Director of the Graduate Program at The University of Texas-Pan American, and currently I am the Paul Thorsen Professor of Psychology (including parapsychology and hypnosis) at Scandinavia‘s largest and one of its oldest universities, Lund University where I can supervise doctoral
students in the areas of my professorship (for more information on this click here).

My main areas of interest are:

  • Anomalous experiences (unusual but not necessarily pathological experiences such as mystical, psi-related and out-of-body experiences and parapsychology.

  • Dissociative experiences and disorders, and their relationship to trauma.

  • Hypnotic phenomena and the use of hypnosis for post-traumatic conditions.

  • These three areas are intimately interrelated, and I think that parapsychological experiences can be fruitfully studied under the larger umbrella of consciousness. I also maintain a keen interest in ritual and contemporary performance.

    I think that my main contributions include the first scholarly book on anomalous experiences published by a mainstream editor (American Psychological Association), the clarification of the nature of deep hypnosis phenomenology, the conceptual and empirical basis for the new DSM-IV diagnosis of Acute Stress Disorder and for the link between acute dissociative reactions and trauma. I am currently carrying out or planning research on:

  • the phenomenology and neurophysiology of deep hypnosis, the relationship between hypnotizability, hypnotic inductions, and performance on standardized psi procedures, and

  • an empirically based taxonomy of anomalous experiences.

  • As with everyone else in the field I know, I have had negative impact from my interest in altered states and parapsychology, but that has usually been tempered by the fact that even critics have acknowledged that I take a scientific stance towards the topic. The saddest thing, though, is that recently I have been personally attacked by colleagues in parapsychology who had hoped someone else would get the job I now hold. It has been a sad reminder that often the worst attacks come from those who are closest.

    I believe that the study of parapsychology and altered states of consciousness are basic to the understanding of consciousness and reality, because they strongly hint that there are alternate and equally valid ways of perceiving reality, and that there is a realm of interconnectedness (or embeddedness) that goes beyond the information provided by the senses and by reason.

    One advice to potential students in the field (and I am just passing on what Charley Tart told me years ago): Unless you are independently wealthy and have the patience of the Buddha, I would recommend that you get a degree in an area related to parapsychology (psychology, physics, biology) and that at least part of your initial work is in a “respectable” area that you find meaningful. I have found that people who admire my “conventional” research are more willing to give me the benefit of the doubt when I talk about psi and even more “fringy” topics.

    Buena suerte, good luck, bon chance, lycka till!
